Mucous Membrane Milkshake

This Halloween milkshake is designed to disgust and delight in equal measure. A creamy blend of buttermilk, vanilla ice cream, pineapple juice, and brown sugar gets topped with actual milk skin (that film that forms on heated milk) to create a convincingly slimy “mucous” layer on top.

The base itself tastes great. Buttermilk gives it a tangy richness, the pineapple juice adds tropical sweetness, and the brown sugar rounds everything out with a caramel note. It’s the presentation that makes it a Halloween showstopper.

The milk skin topping is pure kitchen science. Heat milk until it just boils, let it cool until a film forms on the surface, then carefully scoop it off with a wooden spoon and drape it across each glass. It looks revolting and that’s exactly the point.

Chef Tips

• Blend the base until completely smooth before pouring into glasses. The “mucous” effect works best against a uniform background.
• Let the heated milk cool slowly and undisturbed. Stirring prevents the skin from forming.
• Refrigerate the filled glasses before adding the milk skin topping so everything stays cold.

Variations

• Blend in chunks of canned pineapple for “phlegm balls” as the recipe suggests.
• Drop in halved maraschino cherries for a “blood clot” effect.
• Tint the base with green food coloring for maximum gross-out factor at a holiday party.
